  • Patent number: 8894836
    Abstract: A highly reliable electronic device that prevents entry of a plating solution via an external electrode and entry of moisture of external environment inside thereof, and generates no soldering defects or solder popping defects which are caused by precipitation of a glass component on a surface of the external electrode. The electrode structure of the electronic device is formed of Cu-baked electrode layers primarily composed of Cu, Cu plating layers formed on the Cu-baked electrode layers and which are processed by a recrystallization treatment, and upper-side plating layers formed on the Cu plating layers. After the Cu plating layers are formed, a heat treatment is performed at a temperature in the range of a temperature at which the Cu plating layers are recrystallized to a temperature at which glass contained in a conductive paste is not softened, so that the Cu plating layers are recrystallized.

  • Patent number: 8292438
    Abstract: A projection image display device includes a light source; an illumination optical system that uniformly irradiates a surface of an image modulating element (primary image surface) with a light beam emitted from the light source; and a projection optical system that performs with respect to a screen (a secondary image surface) extended projection on image information provided at the primary image surface and modulated by the image modulating element. The projection optical system includes a first optical system having a positive refractive power, and a second optical system having a concave reflecting surface. The first optical system has a common optical axis at which all optical components of the first optical system have rotationally symmetric surfaces, and a screen shift function that causes the secondary image surface to be moved by moving at least one of the optical components of the first optical system substantially perpendicularly to the optical axis.

  • Patent number: 8217374
    Abstract: There is a need for providing a projection optical system that is appropriate for maintaining high resolution with low distortion, miniaturizing a reflector, decreasing the number of reflectors, and decreasing the depth and the bottom (or top) of a display used for a rear projection television, for example. The projection optical system according to the invention enlarges and projects images from a primary image surface existing at a reducing side to a secondary image surface existing at an enlarging side. The projection optical system has a first optical system L11 and a second optical system L12. The first optical system L11 forms an intermediate image (position II) of the primary image surface. The second optical system L12 has a concave reflector AM1 that forms the secondary image surface resulting from the intermediate image. A light beam travels from the center of the primary image surface and to the center of the secondary image surface and crosses an optical axis.
